 By law, manufacturers must provide the data to hazardous material users.

 MSDS tell the user how to use, store, and dispose of hazardous material.

 You can see an example of a MSDS on pages 19-3 & 19-4.

 According to OPNAVINST 5100.19, all hands are required to follow the guidelines when using MSDS.

 The major concern of Navy personnel aboard small boat is safety of the passengers and crew members.

 Deck Safety: The weather decks of a ship are extremely hazardous places, particularly on small ships. Whenever working out on a weather deck such as in handling lines or when involved in underway replenishment you must wear an inherently buoyant lifejacket.

 DO not sit or lean on lifelines. They are safety barriers to prevent personnel from falling or being washed over the side.

 Smoking is prohibited on the flight and hangar decks and in all fuel and ammo-handling spaces.

 Keep the land deck area free from loose debris, known as foreign object damage (FOD).

 FOD could be blown about by the downwash from the blades of a helo or sucked up by jet intakes.

 Do not paint scaffolds because the paint could conceal defects.

 If handling cargo with a hand truck remember going up or down a ramp, keep the load below you. Thus you pull the load up, and push it down.

 When working aloft, always obtain permission from the ODD Use caution as radio and radar transmission, even from other ships can induce a charge in guy wires, stays, ladders and other metal fittings. The voltages set up in a ships structure or section of rigging by electromagnetic radiation (EMR)can shock or burn you.

 When working over the side, you must wear a standard Navy safety harness with a safety line attached and tended by someone on deck. You must also wear an inherently buoyant life jacket.

 Use lifelines and safety belts when working on a boatswains chair or on unguarded scaffolds above a height of 10 feet

 While the ship is underway, you must be given permission by the CO to work over the side.

 Steam lines run throughout a ship, however most accidents involving steam occur in engine rooms and firerooms. Live steam is often invisible and it is always dangerous.

 Never enter a closed space until it is certified safe by a gas free engineer.

 All closed spaces will be ventilated for 24 hours before entering. Also the space has to be recertified every 8 hours by the gas free engineer.

 If you need to use an internal combustion engine in a closed space the exhaust is vented to the open atmosphere to avoid carbon monoxide poisoning.

 Carbon dioxide is frequently found in refrigerator spaces, because of lack of ventilation and the fact that food slowly absorb oxygen and give off carbon dioxide.

 The purpose of the equipment tag out bill is:
- To provide a safe procedure for personnel to prevent the improper use of a component, system, or equipment.
- To provide a safe procedure for personnel to use when operating an instrument that is unreliable. This procedure uses labels instead of tags (ie, out of calibration)
- To provide separate safe procedures for personnel to accomplish PMS.

 The CO must ensure that all personnel know and comply with all applicable safety procedures of the tag-out system.

 The OOD keeps track of the systems being tagged out and the condition of the readiness of the ship.

 Engineering officer of the Watch (EOOW) keeps up with the status of the engineering plant and how the tag-out bill effects the readiness of the plant.

 Authorizing Officer signs the final authorization placing the equipment/system off line for repairs or maintenance.
 Person attaching the tag: The person who attaches the tag (along with the person who will second check the tag) can make or break the tag-out system. The person hanging the tag actually shuts a valve or secures a switch that takes a piece of equipment off line for repairs or maintenance.

 The person checking the tag is also very important in the tag-out procedure. This process is called second-checking. The second checker examines the tag to ensure they are where they are supposed to be and the valve or switches are in the correct position.

 Tags, labels, and logs are used in the tag-out system to ensure personal safety and equipment from being damaged.

 Danger- Red tags: means a certain danger exists if the system status is changed.

 Caution-Yellow tags: these tags usually have specific instructions about the use of the equipment.

 The two labels that are associated with the tag out system are:
- Out of commission (RED): used to identify instruments that give incorrect measurements because they are unreliable.
- Out of Calibration (ORANGE): used on gauges and devices when their calibration is overdue.

 The number of tag-out logs depends on the size of the ship

 The tag-out log is used to control the entire procedure.

 A copy of the main instruction and any other amplifying directives are found in the front of the tag-out log.

 The tag-out log has three parts:
- main instructions
- DANGER/CAUTION tag out index and a record of audits
- CLEARED DANGER/CAUTION tag-out record.
